Patent DE-3233203-A1 (DE)
Title: Protection relay for electrical machines
Inventor: GARN WALTER DIPL ING
IPC: H02H7/08
Filed: 1982-09-07
Abstract: The invention relates to a protection relay for electrical machines, which protection relay does not operate using the constant triggering value which was normal in the past and was generally set when the protection device was brought into use and which resulted in a disconnection when it was exceeded without the capability in this case existing to take into account those factors which can significantly influence the behaviour of the machine, such as changed environmental influences, the quality of the coolant or of the cooling, changes in the environmental temperature and more complex load conditions etc. These factors can lead to destruction of machine parts even before the set limit value has been exceeded and, on the other hand, triggering can occur which would not yet be necessary because of the changed situation. The relay according to the invention prevents excessively late or unnecessary switching off in that the triggering values are continuously regulated during operation of the machine on the basis of measurements of machine parameters and their assessment in computation circuits, in the sence of reliable current limiting.

Patent DE-3239984-A1 (DE)
Title: Electrical apparatus supplied via cables
Inventor: BOERNER GERHARD
IPC: H01B17/58
Filed: 1982-10-28
Abstract: An electrical apparatus is proposed in which an apparatus part (15) is provided with a holder (16 to 21) for the detachable attachment of a section of the power cable (13). A sleeve (21) which is open on the longitudinal side is allocated to a rod-shaped part (15) such that it can be clamped thereon. A longitudinal cam (26) of the sleeve (21) engages into a recess (17) by means of latching troughs (18, 19). The length of the longitudinal cam (25) and that of the recess (17) are matched to one another, and are preferably equal to the length of the sleeve (21). In the case of the longitudinal cam (25) which is latched into the latching trough (19), the sleeve (21) releases an insertion trough (16) for a power-cable section in the part (15). The insertion trough (16) is longer than the sleeve (21) so that the power cable (30) can be passed out on both sides. If the sleeve (21) is rotated, it is initially spread apart in order subsequently to engage into the latching trough (18) with the longitudinal cam (25). The power cable (13) is now secured by the sleeve (21). The sleeve (21), which is preferably produced from flexible-elastic synthetic material, and the recesses in the rod-shaped part (15) can be produced easily. The mounting of the sleeve (21) is very simple. Once mounted, the sleeve (21) is connected in a captive manner to the rod-shaped part (15). <IMAGE>

The line inlet part, which is formed on the handle piece at a distance of about 10 cm from the reel, ensures the smooth and reliable introduction of the fishing line into the body of the telescopic fishing rod. <IMAGE>
Patent DE-3308986-A1 (DE)
Title: Circuit arrangement for a digital telephone station
Inventor: PETRY SIGMAR DIPL ING
IPC: H04M1/60
Filed: 1983-03-14
Abstract: The invention relates to a circuit arrangement for a digital telephone station, where, for example, the feed voltage for the hands-free microphone amplifier is connected to the telephone station only by a code of the telephone system, and this code is triggered, only by a preceding code, from the telephone station to the telephone system when the hands-free key is pressed. If the code is inadvertently or maliciously transmitted from the telephone system to the telephone station, the hands-free microphone amplifier is then activated. This is intended to be prevented. This is achieved by inserting a contact in the feed circuit of the hands-free microphone amplifier, which contact does not close until the hands-free key is actually pressed.

Title: Automatic original feeder for photographic copiers
Inventor: MASSENGEIL HANS-ADOLF
IPC: B65H31/36
Filed: 1983-04-12
Abstract: The preferably transparent cap (10) for the stack (12) of an automatic original feeder is provided on its underside, which faces the stack, with guide ribs (10b) and support ribs (10c) for the originals returning to the stack (12) after exposure. In order to obtain as small as possible a contact surface with the originals, or to avoid static charging of the originals from impeding the transport operation, the support ribs (10c) are set back with respect to the guide ribs (10b) so far that normally only the bounding edges of the guide ribs (10b) come into contact with the original. The lateral position of the guide ribs (10c) is selected such that the guide ribs are at a distance from the lateral edges of the formats, which have been processed in the original feeder and fed at a common lay edge, that is large enough to avoid interlocking of the support ribs with these edges. <IMAGE>

Due to the single piece design of the rotary part which combines the functions of a driving pinion and a driver part a lower overall width can be achieved. <IMAGE>
Patent DE-3319944-A1 (DE)
Title: Device for the read/write operation of a frame buffer
Inventor: ROEHRLE JOSEF DIPL ING
IPC: G09G5/00
Filed: 1983-06-01
Abstract: If data discontinuously generated by a processing device (VE) are to be continuously displayed by means of a display device (SG), it is necessary first to temporarily store the data in a frame buffer (SP) which is read out in accordance with predetermined display routines. In this arrangement, the reading-out occurs relatively quickly but the data are then transformed into a picture signal with the aid of a video interface (U2), this conversion in each case occurring during a display phase which is relatively long compared with the time for the reading-out. To prevent picture disturbances by simultaneously writing and reading the frame buffer (SP), a writing-in is prevented during the reading-out of the frame buffer (SP). However, the frame buffer (SP) is available for writing in data from the end of the reading-out to the end of the in each case current display phase at a maximum.

Title: Method for the operation of an internal combustion engine and an internal combustion engine functioning according to the method
Inventor: LATSCH REINHARD DIPL ING DR
IPC: F02B19/12
Filed: 1983-08-30
Abstract: The internal combustion engine functioning according to the method has at least one main combustion chamber (10), an ignition chamber (11) producing an ignition flame with at least one injection duct (25, 26) leading to the main combustion chamber (10) and an assigned ignition device (49), a sensor (12) with differentiator (45) connected on the output side as actual value transmitter, a set value transmitter (17) and a governor (18, 19, 20). The sensor (42) detects the pressure in the main combustion chamber (10) and the differentiator (45) indicates the timing of the highest combustion pressure. The set value transmitter (17) emits signals at that angle of rotation of a crankshaft (12a), at which the highest combustion pressure is to occur. In the event of any deviation of the actual value from the set value, the governor (18, 19, 20) adjusts the temperature of a heating resistor (28) and thereby the temperature of the mixture inside the ignition chamber (11). If the actual value occurs too late, greater heating leads to more intensive ignition flames and these cause accelerated combustion of operating mixture inside the main combustion chamber (10). <IMAGE>

Title: Frame of a die-forging hammer
Inventor: TRISSNAK KARL
IPC: B21J13/04
Filed: 1983-11-22
Abstract: There is a frame in which uprights (2) are provided on an anvil (1) on which is secured an anvil insert (6). It is desirable if, although, at the forging temperature, the anvil insert is supported against bearing surfaces of the uprights, it should not exert a bursting action on these and that the bursting action is avoided by avoiding a highly fracture-prone screwed joint. This is achieved by the fact that the outer sides (8) of the anvil insert (6) exhibit a clearance relative to the associated bearing surfaces (5) of the uprights (1) at room temperature and that long screws (10) which are screwed into the anvil and fasten the anvil insert (6) to the anvil (1) extend vertically right through the anvil insert. The lateral clearance between the anvil insert and the uprights is fixed such that, at the forging temperature, it approaches zero, and the length and arrangement of the screws (10) is matched to the conditions of a die-forging hammer. <IMAGE>
